Metal Fight Beyblade Zero G EP15 - The Jet Black Dragon (Part 1)

At the WBBA, Tsubasa tells Zyro and co. that Zero-G stadiums are spreading around the world and wants them to demonstrate it to other bladers. They accept it and split up to different places to show how the Zero-G stadium works. Zyro arrives at a different BeyPark and the bladers challenges him to a battle. Shinobu defeats a blader and the others are ready to challenge after watching to use the Zero-G stadium. Kite and Eight arrives at another BeyPark and battle each other to show the Zero-G stadium. They launch their beys and the bladers become amazed by the battle. Pirate Orochi attacks Guardian Leviathan but it has no effect on it. Kite sends Leviathan to the center of the stadium, but Eight has Orochi to stop it. A blader in the shadows launches his bey and knocks Orochi and Leviathan out of the stadium. His bey returns to him and leaves. Ren arrives at BeyPark and finds Takanosuke there defeating a blader. He is training to defeat Zyro and Shinobu. Ren decides to him battle again to demonstrate the Zero-G stadium. They launch their beys and Thief Phoenix spins around the stadium to attack Archer Griffin but is countered. Griffin attacks Phoenix but its spin track changes to counter the attack and pushes back Griffin. As both beys push each other back, a bey is launched into the stadium and attacks both of them. The blader appears and his bey, Ronin Dragoon, is spinning in left rotation shocking Ren and Takanosuke. It stops the Zero-G stadium and attacks Griffin and Phoenix defeating both of them. Dragoon returns to the blader and Takanosuke asks who he is. The blader tells them his name is Sayko Kuroyami.
